Application filed fleptember 13, 1519. Serial 1'30. 323,505.

To aZZ whom it may concern Be it known that l, WILIJAM Manes, a citizen of the United States, residing at the city of St. Louis, in the State of llissouri, have invented certain new and useful improvements in Clutches, of which the foliowing is a specification.

This application is a continuation of an earlier as to all matters common to the two applications. That earlier application was given Serial No. 261,181 and has since resulted in the issuance of Patent No. 1,318,- 892 dated October-14, 1919.

This invention is an element of a machine adapted to cut off lengths of material from stock fed to a cutting machine, which is r0- vided with knives or cutters. This mac inc is adapted to cut any kind of material such as metal, cloth, or paper, and is especially useful for cutting strawboard, pasteboard,

plasterboard, container board, fiber board, chip board, corrugated paper, double-faced paper, paper tubes, felt, veneer, and the like.

in preparing articles for the market and blanks for boxes and lids that are selling in large numbers and of a standard size, or of standard sizes, it is necessary that the cutting shall be done by automatic machinery, and that each piece, when cut, shall be of size identical with its fellows. To accomplish this, an automatic feed, an accurately timed cutting operation, andan instantaneous release and continuation of feed are essential. To accomplish this last-mentioned effect is the purpose of the clutch more particularly herein described, illustrated, and claimed.

This clutch is ada ted for "use not only.

in cutting machines, ut in any other kind of machinery, and its especial advantage is for use in machines where it is necessa or desirable that the clutch shall take hold and be released with great celerity.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a front elevation;

Figure 2 is a side elevation taken on the line 2-2 in Figure 1, looking in the direction indicated by the arrows;

Figure 3 is a sectional view on the line 3-3 in Figure 2;

Figure 4: is a side elevation on an enlarged scale, parts being brokenv away; and

Figure 5 is a similar view, I

The above-mentioned clutch is construct ed and operates as follows: A driving ring 1 is fastened by screws 2 to the driving.

gear 3. Rollers 4-, iocated in the notches 5 and-between legs 56 in the cage 7, are adapted to roll on the inclined edges 8 of the rod 16 disengages the end of rod 16 fromshoulder 17, spring 11 pulls cage 7 in one direction towards clutch disk 14-, with the result that rollers 4 travel each one up its adjacent incline 8 on the peripheral edge of disk 10, with the result that each roller is thus forced into contact with the inner periphery of driving ring 1, thereby producing a wedgingeiiect that causes clutch disk 14, driving ring 1, and roller-cage 7 to travel as one, thereby rotating shaft 18, because disk ,10 and clutch-disk 14 are both keyed thereto by key '19, while driving ring 1 is attached by screws 2 to gear3. Shoulder 17 is on the cage 7 I Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claim.

I claim:

A clutch mechanism comprising a spur gear. of conventional form having a hub, a web extending therefrom and having a peripheral toothed portion which extends at right angles to said web on either side mechanism and having its peripheral surface closely fitting against the inner surface of the peripheral portion of said gear and abutting against the web of said gear, said annular memberbeing detachably secured b meansof bolts to said web, a driven sha t upon which the hub of said gear is rotatably mounted, an inner clutch ring keyed to said shaft adjacent to said web and having its peripheryspaced from the inner surface of the first mentioned annular member, rollers positioned in said spaced, a cage for controlling said rollers, 21 seeend ring keyed in said shaft 011 the ether side sf said inner clutch ring from said gear, said second ring presenting en annular shoulder toward said gear, said roller cage having an snnuiar portieri seesed on said shoulfler, parallel projeetiens on said cage extending inifie the space he'fiween the first smmflar member the inner c'iut ch ring for pesieienirrg 10 eon'trefiisg said reH-ers, en ereuste recess messes opening euizwerdly toward said second ring, a spiral spring located in said recess arfi resiliently connecting said second ring @1161 said rolier cage, and a manually controlled means for preventing said spring from causing said rollers 420 operatively engage said clutch member.

in testimony whereof I hereunto sfiix my signature.
